Re: Kyocera 7002i thick solid black line

We put a new transfer belt in it today and will see what happens, I'll report back on if it fixed it or not.

Was told by my parts manager that the HV board was replaced. Found out by the last tech that this was not the case..replaced the board and so far so good.

Well we put in a new transfer belt assembly and it hasn't done it since until yesterday and now again today only this time is was worse with almost half of the screen black but little white lines in between the thick black ones. I am to the point now where the HV board is the last idea to do on this. Have you had anymore issues after you replaced yours?

Now that the problem is occurring more on a regular basis, I would suggest trying to isolate the problem by turning the power off during the print process and looking at the printed image on the drum. And then on the transfer belt. It may be tricky shutting the power off at the correct time. Probably gonna take a few tries. But at least you can use this method to isolate the problem.

Changing the power pack for the main charge has taken care of this issue for me. 3 weeks so far and counting.

As i has written in post #15
1 case would solved after exchange from complete conveying unit.
Maybe a grounding problem from transfer belt/ separation needle.
Belt gets in contact to drum, because of sometimes missing ground from belt, the transfer voltage/ or separation voltage will shorten the drum surface and we get thick black line.

Did all that with no change. So far the only thing that fixed my problem was replacing the main charge HV board.

Thanks for responding, we are putting a new main high voltage in it tomorrow morning and will see what happens but from your experience that sounds like it might be culprit. If it does it again I'll look into the conveying section.

In my case transfer belt replacement solved the issue.There is a bulletin to change the new type transfer belt unit with the Yellow dot on its body. long procedure but its really helps a lot. good luck.

Thanks, we tried that a few weeks ago and it's still doing it. It has a new maintenance kit in it and now a second new transfer belt. If the HV board doesn't fix it I'll look into the conveying section.

Your sample looks like a copy. if your arrows indicate direction of scan, and you notice that the black area has a margin, then the machine appears to be writing that black line. You might want to consider taking a closer look at the scanner. You may have an image processing problem or something happening in the scanner.

Re: Kyocera 7002i thick solid black line

Ok so they called back and it is still doing it, it has a new drum, new developer, new transfer belt, new main high voltage. Only thing left to do now is try the conveying section.

It does this on copies, prints and faxes if there was any confusion so it isn't scanner related.

Don't forget that the scanner also has a margin erase. If the original has lines out to the edge and is scanned the scanner will chop off those edges.

We are trying a new conveying section now as it has a new drum, developer, transfer belt and main high voltage board. Hopefully this will take care of this.
